# AriaIPRWAVault

**Inherits:** UUPSUpgradeable, IAriaIPRWAVault, ERC721Holder, VaultAdmin, VaultFundraise, VaultView, Whitelist

Main contract orchestrating vault logic by inheriting fundraise, admin, and view functionalities. Directly implements fractional token claim function.

## Functions

### constructor

**Note:** oz-upgrades-unsafe-allow: constructor

```solidity
constructor();
```

### claimFractionalTokens

Caller claims the fractionalized IP tokens from fundraise, only when the vault is Closed.

```solidity
function claimFractionalTokens(address usdc)
    external
    override
    nonReentrant
    whenNotPaused
    returns (address fractionalToken, uint256 amountClaimed);
```

**Parameters**

| Name   | Type      | Description                                                                                                                                                           |
| ------ | --------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `usdc` | `address` | The USDC address used to deposit funds into the fundraise. As it can change over the fundraise lifetime, it is required to specify the USDC address used for deposit. |

**Returns**

| Name              | Type      | Description                                |
| ----------------- | --------- | ------------------------------------------ |
| `fractionalToken` | `address` | The address of the fractional token        |
| `amountClaimed`   | `uint256` | The amount of the fractional token claimed |

### claimFractionalTokens

Caller claims the fractionalized IP tokens from fundraise, only when the vault is Closed.

```solidity
function claimFractionalTokens(bytes32[] calldata _proof, uint256 _amount)
    external
    override
    nonReentrant
    whenNotPaused
    returns (address fractionalToken, uint256 amountClaimed);
```

**Parameters**

| Name      | Type        | Description |
| --------- | ----------- | ----------- |
| `_proof`  | `bytes32[]` |             |
| `_amount` | `uint256`   |             |

**Returns**

| Name              | Type      | Description                                |
| ----------------- | --------- | ------------------------------------------ |
| `fractionalToken` | `address` | The address of the fractional token        |
| `amountClaimed`   | `uint256` | The amount of the fractional token claimed |

### \_authorizeUpgrade

```solidity
function _authorizeUpgrade(address newImplementation)
    internal
    override
    onlyRole(AccessControlStorage.DEFAULT_ADMIN_ROLE);
```

### \_checkClaim

```solidity
function _checkClaim(AriaIPRWAVaultStorage.VaultLayout storage $, address usdc, address claimer) internal view;
```

### \_checkLegal

function _checkLegal(address legal, address claimer) internal view;
```

### \_mintAndEmitEvent

```solidity
function _mintAndEmitEvent(
    AriaIPRWAVaultStorage.VaultLayout storage $,
    address usdc,
    address claimer,
    uint256 amountClaimed
) internal;
